enrich-ioc

enrich-ioc is a skill for Claude Code, Codex from dandye/ai-runbooks. It costs 57 tokens per session (769 once invoked), scanned A, original, Apache-2.0.

A threat-intelligence workflow for investigating one Indicator of Compromise (IOC), such as an IP address, domain, file hash, or web address, using reputation data and security logs.

In plain words
What is it for?
Use it to check whether a single indicator is malicious, suspicious, or clean, review its related infrastructure or malware, and see matching entities in your environment.
Why use it?
It brings external threat context and internal security findings together, including whether the indicator was seen in the SIEM.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

enrich-ioc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Enrich IOC Skill

Perform standardized enrichment for a single Indicator of Compromise (IOC) using Google Threat Intelligence (GTI) and Chronicle SIEM.

Inputs

  • IOC_VALUE - The indicator value (e.g., "198.51.100.10", "evil-domain.com", "abcdef123456...", "http://bad.url/path")
  • IOC_TYPE - The type: "IP Address", "Domain", "File Hash", or "URL"

Workflow

Step 1: GTI Enrichment

Based on IOC_TYPE, call the appropriate GTI tool:

IOC Type Tool Example
IP Address gti-mcp.get_ip_address_report get_ip_address_report(ip_address="198.51.100.10")
Domain gti-mcp.get_domain_report get_domain_report(domain="evil-domain.com")
File Hash gti-mcp.get_file_report get_file_report(hash="abcdef123...")
URL gti-mcp.get_url_report get_url_report(url="http://bad.url/path")

Store key findings in GTI_FINDINGS:

  • Reputation score
  • Classification (malicious, suspicious, clean)
  • Key relationships (contacted domains, IPs, etc.)
  • Associated malware families or campaigns

Error Handling: If GTI fails (quota exceeded, IOC not found), note the limitation and proceed with SIEM enrichment.

Step 2: SIEM Entity Lookup

secops-mcp.lookup_entity(entity_value=IOC_VALUE)

Store in SIEM_ENTITY_SUMMARY:

  • First/last seen timestamps
  • Related alerts
  • Associated assets/users

Step 3: SIEM IOC Match Check

secops-mcp.get_ioc_matches()

Check if IOC_VALUE appears in results. Store Yes/No in SIEM_IOC_MATCH_STATUS.

Required Outputs

After completing this skill, you MUST report these outputs:

Output Description
GTI_FINDINGS Summary of GTI report (reputation, classification, relationships)
SIEM_SUMMARY SIEM entity context (first/last seen, related alerts)
IOC_MATCH_STATUS Yes/No - whether IOC appears in recent threat feed matches
THREAT_SCORE Numerical threat score (0-100) based on GTI reputation
MALICIOUS_CONFIDENCE Confidence level: high, medium, low, or none

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
